1992 GMC Sierra - Page 2 - Answered Questions & Fixed issues

Sounds like a problem with the censor or a bad pig tail, try unplugging the pig tail and sticking a paper clip in both sides and then turn the ac on, that will tell you which it is

If you unplug sensors with engine running it should set codes,if not the ecm is most always the problem(assuming your ck eng light is coming on)

I would say the problem is inside the radio itself. I have no idea if anyone repairs these units anymore or if any good used ones are available.

It should be in the fuse panel.

if it is just overdrive that isnt working it will possibly be the electronic solenoid for overdrive in the transmission that needs replaced...

pin ??? front axel need more info

Could be obvious like plugs, or could be vacuum leak. Check where the hose enters the valve cover.

I'd use 90W gear oil.

If you let go of steering wheel and step on brakes does the wheel vibrate? I'd say its either warped rotors, power steering malfunction, or possible wheel bearing, although if wheel bearing you should feel/hear a hum which would get louder depending on which way you turn the vehicle.

The GMC 1500 Sierra have several engine sizes, hope this helped...

Good luck, and remember rated this. TY for using Fixya.

change the light stalk they are prone for breaking down

check the steering arm damper shocky as it may be failing and not providing the proper dampening effect to the steering. Check the wheel bearing adjustment and condition.

check the trans fluid level first ,if it is low add some , about 2 qts.will make it work then check for leaks underif is leaking between the engine and transmission you have to take it to the transmission shop

The ground should connect to the motor and the motor should connect to the body or chassis. Pour some water on the connection to the engine and the battery terminals. If it is a bad connection things should improve. If you jump start, the donor vehicle needs to be running at a fast idle.

IGNITION MOGULE

loose connection ? check all wires from battery, clean battery & terminals, check alternator wires, grounds, etc., thoroughly check all grounds, everywhere !!!!!!!! inspect the headlight switch for loose connection, trace all power wires & ground wires for loose or bad connection . what else could it be ?????????????/ check all wires, especially back to fuel pump, rear tail lights, etc., make sure those ground wires are making a good connection, DO YOU UNDERSTAND ???????
